videl is a good unit and leads some good teams but every single piece of peppy gals content has been made with the 120 leads in mind and defenders of justice can be ran entirely with gotenks units.
SSBBKKKKKKKKK is mediocre but ahs a cool active skill that is kind of hard to activate.
gotenks and the kids are pretty good units but they rely a little n rng and gotenks takes a while to transform, nd evne then he has a timed buff.
teq janemba is good before transforming but when he does he loses guard, which is probably why you won't transform with him at all.
I've never seen anyone talk about the blue boys. i used a rainbowed one in joined forces and it was mediocre imo.
teq gobros are still good albeit they need to build up a little. i use them all the time on battlefield.
lr teq gogeta seems real good but i kind prefer vegito. i don't remember if the will cost 400 coins, i think lrs are all 500 coins.
teq whores leads 2 decent categories, one of them is basically the goku team + the whores, it is also the only other team where lr brolly trio and gohan and krillin can be used together.
Everyone else + some of the mentioned will be on the step up banners or will take a long while before being available for purchase with coins.
